Firefly Lane Cast Hint At What Tully Did In Cliffhanger Finale

*Warning - Firefly Lane spoilers below*

Firefly Lane on Netflix has got everyone talking recently, whether they're swooning over hunky Max Brody, fan-girling Katherine Heigl and Sarah Chalke or majorly 'shipping the friendship between Tully and Kate.

But it's the massive cliffhanger at the end which has dominated conversation - why are Kate and Tully no longer friends?!

The bombshell is dropped at the end of the series - in the final moments of episode 10 - when we see the pair at Kate's dad's funeral.

It appears that Tully has done something to upset Kate, but the show doesn't reveal what.

Of course, people are speculating on social media as to what went down for the pair to fall out.

One theory is that Johnny (Ben Lawson) could play a part, seeing as the last episode we see his squad head off to a mine in Iraq, with no hint as to what lies ahead for him, and whether he survives.

Whatever happened there, perhaps this has created some animosity between Tully and Kate - say, if Tully kept the outcome from her friend, or wasn't there for her in her time of need.

Another theory is that Tully may have slept with Johnny, if he survived.

However, actor Ben quickly put an end to that speculation during an interview with Us Weekly: "I can tell you that it doesn't involve Johnny," he said.

Speaking in an interview with Oprah Magazine, Katherine Heigl also enforced that she wasn't keen for that to happen. In fact, she promised to "fight to the death" to ensure that Tully would never betray Kate to that degree.

"It cannot be that Tully sleeps with Johnny. I don't think any friendship would come back from that," she said.

Speaking to The Wrap, actress Sarah Chalke said that she wasn't even privy to any gossip about what went down between Tully and Kate.

"I don't even know, to be 100 per cent honest, what the actual last straw is," she said. "I know what it is in the book, but I don't know if Maggie [Friedman, the showrunner] will choose to use that or something else, if we're lucky enough to get to continue for another season."

Meanwhile, showrunner Friedman told Entertainment Weekly: "I knew that Tully and Kate were going to be estranged at the end of the season, but I didn't know how I was going to dramatise that.

"I knew we were working towards that signpost because I felt like a good cliffhanger for season one is: 'Oh my God, wait, these "Firefly Lane girls forever" are suddenly not? What happened?'

"I wanted to leave the audience with some big questions."

And that you did, Maggie...

Now we can't confirm the series will follow the book, but if it does then the pair's argument comes after Tully embarrasses Kate on her TV show.

It comes after Kate is invited on The Girlfriend Hour to talk about the problems she's having with her daughter Marah (Yael Yurman), but goes to to suggest she's somehow a bad mother instead, with a psychologist even chiming in and criticising "controlling, domineering" mothers like her for "damaging" their kids.

Speaking on this incident, Katherine Heigl has expressed her doubts that this incident would be a "strong enough" reason for the pair to part ways as friends.

So, unfortunately, it looks like we're just going to have to wait and see...
